ELEKS vs Sigma Software Group: overview

ELEKS

ELEKS predates Ukraine's independence as a company: it opened in Lviv in 1991 and has been operating continuously ever since, growing past 2,000 employees along the way. It has built long-standing practices in healthcare, insurance, and financial technology, with case studies spanning both custom product development and enterprise system modernization. Longevity gives ELEKS a stable delivery process and a deep pool of senior engineers, though it also means the company's public marketing emphasizes heritage more than any single narrow technical specialty.

Sigma Software Group

Five friends started Sigma Software Group in Kharkiv in 2002; the company now runs roughly 40 offices across 19 countries with more than 2,100 professionals. It runs practices across gaming, aerospace, fintech, and automotive engineering, positioning itself as a technology consulting and product development partner rather than a pure staffing vendor. The company's own relocation and expansion since the 2022 full-scale invasion has moved a meaningful share of delivery capacity outside Ukraine, which buyers who specifically want Ukraine-based delivery should confirm directly.
